罗布泊“耳纹”成因与电磁感应电导仪测量值相关性初探

Preliminary Study on Correlation between the Contributing Factor of Lop Nur Great Ear Rings and Electromagnetic Induction Measurements (EM38)

应用EM38电磁感应电导仪测量法调查了罗布泊“耳纹”地区盐壳电导值,对干盐湖沉积物采取不同尺度和不同空间分辨率的取样与测量。研究结果表明,盐壳土壤EM38电导的各特征参数值均表现出明显的空间变异性,“耳纹”的形成和电磁感应电导所表征的物理量存在较好相关性:“耳纹”黑色区域电导值较高,白色区域电导值较低。

The Electromagnetic Induction Measurements （EM38） were applied to investigate electromagnetic induction of the salt crust in Lop Nur Great Ear region and the deposit sampling and measurements were made in different scales and varied space differential rate. The results showed that： Each characteristic parameter values of the salt crust soil all expressed distinct space variability. There is better correlation between the formation of the Great Ear and the physical quantity expressed by the electromagnetic induction. Then the electric conductivity value in the black district of the great ear is higher than that in white region.
